sir mel, favor po pa pm din po sa 2 way.. TIA

Kaka PM ko lang po sa inyo :-)

sir mel
pwede bang 220uf na 63v wala kasi akong mabili na 270uf 63v na ikot ko na ang raon wala talaga akong makita
thanks

rascal101 · « **Reply #153 on:** Oct 31, 2010 at 09:06 PM »

Puwede rin po iyan although mas maganda kung mas mataas. Kahit po iyung boltahe mas maganda kung mas mataas sa 63V.

Maraming shops sa Quiapo mayroon 330uF, 470uF at mas mataas na capacitors. Bili na lang po kayo ng non polar capacitor para hindi niyo na kailangan mag back to back.

thanks mel

sir mel.

question lang po ulit pag non polar po ba same din po ba yung value?
thanks

rascal101 · « **Reply #156 on:** Nov 02, 2010 at 04:00 PM »

Kung gagamit po kayo ng non-polar ang value po na gagamitin niyo ay kalahati ng nakalagay sa schematic. Ang nakalagay kasi sa schematic ay 270uF so ibig sabihin ang gagamitin niyo ay 135uF. So, imbes na dalawang 270uF na naka series isang 135uF na lang. Dahil hindi pangkaraniwan itong value na ito, puwede na rin iyung 150uF o 180uF

sir mel,

tanong ko lng po,mission m74 ang speaker ko dalawa po ang woofer, dapat po ba lagyan ko ng capacitor bawat woofer gusto ko po kasi nasa loob ng box sensya na po sa abala salamat po

rascal101 · « **Reply #159 on:** Nov 04, 2010 at 08:34 PM »

Bro,

Sa tweeter dapat ilagay iyung snubber capacitor pang control ng mga "highs".

Sa woofer dapat gamitan mo iyung 6turn choke.

rascal101 · « **Reply #160 on:** Nov 05, 2010 at 08:26 AM »

At this point would like to summarize the suggestions or approaches to maximize a speaker:

(1) Use of snubber circuit - to reduce high frequency peak voltage; subjectively to minimize sibilance.

(2) Use of choke or inductor - to improve rate of charge/discharge of current; also a small choke stores low amplitude signals better; subjectively to improve mids and highs.

Since this may not be enough for some people would like to offer one approach to improve on item 1.

It would be a good idea if the signal being "improved" by the snubber is made "better". To do this we will be using the time tested approach of using smaller and better capacitors placed in parallel with C1 and C2. So that it is cost effective we will just put 2 capacitors in parallel.

Edit 11/07/2010

Here are some suggestions ...

(1) C1 and C2 = 220uF, place a 2.2uF/50V (electrolytic cap) and 560N/50V (mylar cap)

(2) C1 and C2 = 270/330uF, place a 3.3uF/50V (electrolytic cap) and 680N/50V (mylar cap)

nb You may use better capacitors if you want

Sir rascal i have Bose 301 series v and not impressed sa sq nya, what approache is applicable to improve sq specially sa bass. thanks!

rascal101 · « **Reply #162 on:** Nov 06, 2010 at 05:54 AM »

Sir,

May I suggest you choose the inductor method first. We'll just add on to the inductor method after you've done it

Thanks Sir Rascal!

sir mel

wala na po yng 104/474 na 50v mylar cap, 3.3uf/50v electrolytic cap at 680n/50v mylar cap na po ang kapalit thanks po

rascal101 · « **Reply #166 on:** Nov 06, 2010 at 12:00 PM »

Yes Sir. Namali po ako ...

tnx sir mel for helping me pimp my speakers! medyo delayed etong feedback ko sir!

nice thread sir, will try this later... newbie question lang po malaki po ba difference ng snubber sa crossover when enhancing speakers

thanks! thanks!

titopepe · « **Reply #170 on:** Dec 12, 2010 at 03:17 PM »

pwede ba yan gawin sa altec lansing atp3? 8yo na rin naman siya e....

kaso, mang mang ako sa electronics.
marunong ako mag solder, pwede paturo kung panong exact na gagawin?

Bro, medyo rolled off ang highs kapag naka snubber circuit ka. Hindi rin ma sibilant.

Tungkol sa diperensya depende sa pagtimpla mo iyun kasi hindi naman pare parehas ang tunog ng bawat system kaya may range ako na binigay sa snubber resistor at capacitor.

rascal101 · « **Reply #172 on:** Dec 16, 2010 at 10:21 AM »

Yes Sir.

You can try using a 5ohm/5W resistor in series with a 220nF/50V mylar capacitor (223) and solder in parallel with the 10uF/16V capacitor as shown below.

12/19/2010: My bad ... 220nF has 224 marking not 223. 223 marking is for 22nF ...

galing galing sir

! tried it on my creative 2.1 sbs 350 sa sub woofer pa lang he he it went nice... laruin ko pa yung values and will try it on its satellite speakers...

thanks! thaNKs!

rascal101 · « **Reply #178 on:** Feb 10, 2011 at 01:47 PM »

On the choke tweak it is a good idea to add a small resistor in series - 0.1ohm 5W or 2pcs 0.1ohm 5W (which becomes 0.05ohms). Reason here is inductors or chokes require a series resistor to improve current charging and discharging time due to L/R time constant.
